ABSF WROTE:That circuit looks cool and I have bookmarked it in case I need it!

I have already ordered some LM2577-adj and some LM2575-5V and have used a few of them in my projects. They were running cool and has been running for a few weeks without a heat sink.

Last time I also made a one transistor dc/dc inverter to step up 1.5 volts to 3V to light up a white LED. I forgot what is the web site. It was using a NPN and a ferric ring with just a few turns of copper wire for stepping up the voltage. I'll to find the site and post it here. I am sure if the input is increased to 3V, it will be able to get an output of 5V to run a PIC.
